Hole and the sink hole being connected to the small straight passage hole.
Further, the diameter of the big straight-through section it is 1mm bigger than the large straight via hole aperture~2 mm.
Further, the diameter of the small straight-through section it is 1mm bigger than the small straight passage hole aperture~2 mm.
Further, the diameter of the small straight-through section is 2mm~8mm.
Further, the length of the small straight-through section is 1mm~3mm.
Further, the length of the big straight-through section is 3mm~8mm.
Further, the diameter of the overlap is greater than the diameter of the small straight-through section.
Further, the diameter of the overlap is less than the diameter of the big straight-through section.
Further, the overlap is equipped with a circle chamfering far from valve seat side.
The utility model has the beneficial effects that a kind of novel capacitor cover board overall structure of the utility model passes through in explosionproof hole
The interference fit of explosion-proof valve is led directly to tower, is designed double bypass structures of big straight-through section and small straight-through section, is increased lid and tower
The CONTACT WITH FRICTION area of straight-through explosion-proof valve, frictional force greatly increase, meanwhile, it is caught in the left-hand thread structure of sink hole in conjunction with overlap, has
Effect ground has prevented explosion-proof valve obscission.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model
Some embodiments for those of ordinary skill in the art without creative efforts, can also be according to this
A little attached drawings obtain other attached drawings.
Fig. 1 is a kind of novel capacitor cover board vertical view figure structure schematic representation according to the utility model embodiment；
Fig. 2 is the structural schematic diagram of the direction A-A explosionproof hole in Fig. 1；
Fig. 3 is the knot that tower leads directly to explosion-proof valve on a kind of novel capacitor cover board according to the utility model embodiment
Structure schematic diagram.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art's every other embodiment obtained, all belongs to
In the range of the utility model protection.
As shown in Figure 1-3, a kind of novel capacitor cover board according to the utility model embodiment, including lid 1, institute
Lid 1 is stated equipped with explosionproof hole 2, the interior tower being interference fitted with explosionproof hole 2 that is equipped with of the explosionproof hole 2 leads directly to explosion-proof valve 3, described
Tower leads directly to explosion-proof valve 3 and successively includes valve seat 31, the big straight-through section 32 connecting with the valve seat 31 and lead directly to section greatly with described
The small straight-through sections 33 of 32 connections, are extended with overlap 34 far from 31 one end of valve seat in the small straight-through section 33, the explosionproof hole 2 is successively
Including the large straight via hole 22 cooperated with the big straight-through section 32, the small straight passage hole 23, the Yi Jiyu that cooperate with the small straight-through section 33
The sink hole 24 that the small straight passage hole 23 is connected to.
In the present embodiment, the diameter of the big straight-through section 32 is 1mm bigger than 22 aperture of large straight via hole~2 mm.
In the present embodiment, the diameter of the small straight-through section 33 is 1mm bigger than 23 aperture of small straight passage hole~2 mm.
In the present embodiment, the diameter of the small straight-through section 33 is 2mm~8mm.
In the present embodiment, the length of the small straight-through section 33 is 1mm~3mm.
